When the teachers of the imperial academy arrived everything was a little calmer. Their students have eaten well and been cared for well. Making them almost in awe of the children's careful treatment of their own, much to their surprise that there are no adults to supervise the whole thing.
But not all teachers were happy with the identities of the children who rescued one of their own.
It was not a secret that there was plenty of bad blood between schools. It has existed from their competitions that later on turned into grudges. And from these grudges into lifelong enemies. This is particularly strong with old teachers who make big deals over these enmities.
